Web1 day ago · When used as a colouring agent, there are no health risks with use. There is insufficient data on the absorption of chlorophyllin supplements, but there is evidence that it can raise copper levels. Supplementation can cause green discoloration of the urine or stool, as well as tongue discolouration. Chlorophyll c refers to forms of chlorophyll found in certain marine algae, including the photosynthetic Chromista (e.g. diatoms and brown algae) and dinoflagellates. These pigments are characterized by their unusual chemical structure, with a porphyrin as opposed to the chlorin (which has a reduced ring D) as the core; they also do not have an isoprenoid tail. Both these features stand out from the other chlorophylls commonly found in algae and plants. coach trips weston super mare
